52906 PXI延伸卡
PXI延伸卡的功能是将PXI背板讯号延伸至机箱外,再将PXI卡插至延伸卡上,即可在有电源的状况下,轻松检查或量测PXI卡之讯号,为研发或维修人员解决PXI卡放置机箱内,不易检测的问题。
PXI延伸卡可让使用者在系统开机时,隔离送到PXI卡的电压和信号,以便执行热插拔。此延伸卡在每次启动时,皆可提供PXI卡初始化所需的电源。当使用者读取及重新写入配置档时,即可减少PC重新开机的次数。
PXI延伸卡可让使用者利用电压表,轻松量测到PXI标准五组电压之每组电压的消耗功率。延伸卡上具有过电流保护回路,可在PXI卡故障时,避免损坏系统背板或其他相关部件。此外,延伸卡提供Jumper,让使用者自订过电流保护之电流量,另外延伸卡亦具有外部电源之接头,使用者可不需透过背板电源,直接经由外部供电。
